When using an external antenna a 1/4 wavelength is recommended. Ideally use 50 impedance ohm single-core wire, the length of the antenna 433M is about 17cm (1/4 wavelength). When locating the receiver antenna keep it as far away as possible from shielded areas, high voltages, and any other possible interfering frequencies.

ARDUINO TRANSMIT EXAMPLE
Code:
/* FILE:    MXFS03V_433MHZ_MODULE_HCMODU0007_TRANSMIT_EXAMPLE.pde
   DATE:    03/03/13
   VERSION: 0.1
   AUTHOR:  Andrew Davies

This is an example of how to use the 433MHz wireless transmitter module
(HCMODU0007) which is the Tx part of the tranmitter and receiver module pair.
This example makes use of the VirtualWire library written by Mike McCauley.
The sketch will read a value from the analogue input A0 and transmit it as
2 bytes to the receiver module once every second.

PIN  DESCRIPTION      ARDUINO PIN
1    GND              GND
2    VCC (3.5-12V)    VCC
3    TX DATA          D2

ARDUINO RECEIVE EXAMPLE
Code:

   DATE:    03/03/13

   AUTHOR:  Andrew Davies

This is an example of how to use the 433MHz wireless reciever module
(HCMODU0007) which is the Rx part of the tranmitter and reciver module pair.
This example makes use of the VirtualWire library written by Mike McCauley.
This sketch in intended to be used with the Tx example code to recive analogue
input data sent from the transmitting Arduino. The received data is then output
to the UART.

1    GND              GND
2    RX DATA          D2
3    RX DATA          N/A
4    VCC (5V)         VCC

FAQ

Can I transmit to more than one receiver?

Yes, all modules operate on the same channel so any receiver will receive data from any transmitter in range.

Can I receive data from more than one transmitter?

Yes, see above.

What is the fastest data rate I can send using these modules?

You can seen a maximum of 4000 (4Kb/s) bits per second. See comment below.


Can I use this module to send serial data?

Yes, but there are a couple of considerations:

First of all the Tx output pin of the receiver is normally low which means that your start bit will have to be a logic high to be detected by your application. This means a standard serial interface may not work without modification.

Secondly the module has a limited data rate of 4000 bits per second. The main limiting factor is that there is a fixed delay on the rising edge of the Tx pin. This delay get more significant as the data rate is increased which causes the logic '1's' to get narrower. Beyond 4Kb/s the logic 1's start to become too narrow and may cause them to be seen as 0's by the receiving hardware. The reciver's Tx pin will also take approximately 55ms to return low again after receiving data.

hello,

work this module with HT-12D/E for a simple wireless switcher ?

From what I can see from the datasheet the HT12E (no carrier version) should work fine. Data is clocked out at 3KHz which these modules should just about be able handle.

I found now other cheaper decoder IC´s, PT2262 / PT2272.

There are also RF module, as these are already integrated !

Just to let you know that we now have the PT2262 & PT2272 modules (non-latching version) on order and we will be stocking them soon.

Just to let you know that both in the shop and in this thread, the "pinout" image at http://www.hobbycomponents.com/image/da ... Pinout.png is broken.

I've managed to find the pinouts elsewhere but just thought I'd let you know :)

Thanks for pointing this out. We moved to a different hosting company a little while back and it broke one or two links. This should be fixed now.

Has anyone got datasheets for these MX-FS-03V & MX-05 modules, or C code for a PIC?
